The Evolution of Craps: From Hazard to Modern Casinos
Craps is descended from a game called Hazard, played in London coffeehouses in the 17th century. It is a game whose rules were once wildly local, now globally standardized.

Hazard was an English game of chance, documented by the 1640s, though it may have existed earlier. Two players, dice, a shooter. The rules varied wildly by house and region, which was rather the point of an unregulated game.
The modern game descends from this, but through an American lens. What the British played in smoky rooms in Westminster became what New Orleans dock workers gambled on in the 1800s. And from there, what the American military standardized and exported across the globe.
The Rules Drift
Hazard had the following: one player throws the dice. A second player bets against the throw. The outcome depends on the total of the dice. But the threshold values shifted: in some versions, rolling a 3 was instant loss. In others, a 5 was the break point.
When Hazard travelled to America, particularly to New Orleans, the rules simplified and standardized. The "craps" or "crap dice" were rolls of 2, 3, or 12, which lost immediately. A "natural" was 7 or 11, which won immediately.
The game was still local, but the rules were narrowing.
John H. Winn's Contribution
In the early 1900s, a man named John H. Winn, a gaming house operator, standardized the game further. He introduced the "don't pass" bet, the complement to the "pass" bet. He created a symmetric game where both sides had near-equal odds.
Before Winn, craps was a predator game. The house ran it, the house took a cut, and the math favoured whoever controlled the game. Winn's version was a player-versus-player game where the house only skimmed.
This was not altruism. It was business strategy. A game that felt fair would attract more money in volume, even if the house percentage was smaller.
The Point Rule
Winn also refined what is called the "point rule." If the initial roll is neither natural nor craps, that number becomes the point. The shooter then rolls again until either the point repeats (and the pass bet wins) or a 7 appears (and the pass bet loses).
This introduced sequence and tension. A single roll might not resolve the bet. The game now had acts, like a play. You roll the 4. The point is 4. Then you roll again. The tension builds until the 4 repeats or the 7 appears.
This is game design. Winn understood that introducing complexity and pacing could increase the game's appeal without changing the underlying odds.
The Nevada Spread
When casino gambling became legal in Nevada in 1931, craps spread into legitimate casinos. The house now offered side bets: the come bet, the don't come bet, field bets, place bets, odds bets.
Each of these bets has a different house edge. The pass line is 1.41 percent. Field bets are 2.78 percent. Proposition bets in the middle of the table can be 11 percent or more.
A player unfamiliar with craps might walk up and make a field bet and think the game is against them. Knowledgeable players know which bets have favourable odds and which ones are traps.
The game became a test of knowledge as much as chance.
Modern Craps
Online craps, particularly at Pragmatic Play and Playtech, uses an RNG to roll virtual dice. The physics of the physical game do not apply. The dice are not actually rolling. The outcome is determined by algorithm.
But the rules remain the same. Pass, don't pass, come, don't come, odds, field. The nomenclature is unchanged from 1900s New Orleans.
Some players argue that the RNG version is not "true" craps because the physics of the real game is missing. But the actual game rules, the betting options, the odds, are identical.
What is lost is the physical feedback: the weight of the dice, the sound of them hitting the back wall, the speed of the roll. What is gained is accessibility: you can play craps alone against a computer for cents, rather than needing a full table of players and a house to run the game.
The Persistence
Craps has been a casino staple for over a century. It has survived slot machines, poker booms, sports betting expansion, and crypto gambling. The rules that Winn codified in 1912 are still the rules in 2026.
This is unusual in games. Blackjack rules have drifted (3:2 vs 6:5 payouts, late surrender, doubling restrictions). Roulette has variants (American wheel vs European wheel vs single zero). Baccarat has bets the original game did not have (side bets on suited pairs).
Craps has remained stable. The pass bet is still the fundamental bet. The come bet is still the sophisticated alternative. The point rule still drives the game's tension.
Winn's 1912 game and a 2026 craps game at DraftKings are structurally identical. That is rare. That is why craps survived.
